It accepts 0.30 mm thick FFC cable and terminates via solder to the PCB. The Low Insertion Force (LIF) design reduces pad wear during assembly and rework — a practical benefit when the flex circuit sees multiple insertions over the product life. The housing is black polyamide (PA6T) with UL94 V-0 flammability rating, suitable for equipment requiring flame-retardant materials inside the enclosure. Phosphor bronze contacts with tin plating provide reliable electrical connection for low-cycle duty. No pin-compatible direct replacement is listed by JST — this is the active order code for the 4-position, 1.00 mm pitch, vertical SMD FMN connector.","metaTitle":"JST 04FMN-BMT-A-TF(LF)(SN) FFC Connector – 1.00 mm Pitch","metaDescription":"JST FMN series 4-position FFC connector, 1.00 mm pitch, 0.5 A, tin-plated contacts, LIF, SMD, RoHS.
